GRAIN-D O 0 R.

Applicationfiled'september 26, 1914;

To all whom it may concern:

Be 1t known that I, F REDRICK C. SCHMIDT,

acitizen of the United States, residing at St.

Louis, in the State of Missouri, have invented certain new. and useful Improvements in Gram-Doors, of whlch the following is a specification.

This invention relates to improvements in doors and more particularly to grain. car doors. i

The object of my invention consistsin providing a grain car door designed for use in cars where the door frames are of varyingsize to overcome the'present short coming of nailing the doors upon the door frames of the grain cars. I

. A furtherobject of my invention consists in providinga grain cardoor which shall possess the importantcharacteristics of simplicity of construction, efficiency in service for but slight labor.

With the above and further objects in view my invention consists in the combination, arrangement, and details of construction disclosed 1n the drawings and specification, and then more particularly pointed out in the appended claims.

Referring now to the drawings which are merely illustrative ofmy invention, Figure 1 is a front elevation of my invention, .while Fig. 2 is a rear elevation thereof. Fig. 3

isa horizontal section taken on the line 33 .of Fig. 1. Fig. .4 is a vertical cross-sectional view taken on the line 44 of Fig. 1. Fig. 5 is a detail perspective of one of the latching dogs.

Referring further to the drawingswherein similar reference characters designate similar parts 1 throughout the respective views, 1 designates the door frame in general which maybe of any approved deslgn Specification of Letters Patent;

or construction. Adapted to this door frame 18 a door made of a substantially rectangular plank preferably of wood in which are arranged,.at opposite ends, the carriers designated 8 and 4 respectively. The door 2 is to be of any satisfactory size and will be placed in position opposite the door frame by suitable latch mechanism now to be clescribed.

Each of the carriers 3 and l is composed of afl side plate 5 and an end plate 6 preferably extending beyond the edges of. said plate 5. A housing 7 is secured upon both the. side plate 5 and end plate 6 and is formed upon its side 8 with a slot 9 through which projects a latching dog 10, said dog consisting of a hook-shapedmember formed upon its bill 11 with two series of oppositely-disposed notches 12 and 13 upon its opposite edges. A transverse pin 14 is secured to, each of. said dogs at its end opposite to its bill, said pin being secured intermediate its ends upon said dog. Extending in the housing 7 opposite either edge of the slot .9 is an elongated rack bar 15. A pair of these rack bars is provided with the alining notches 16in which the pin 14: is adapted to be placed or lodged.

It will be understood that'the rack bars 15 will be spaced from the side wall or plate 5 to provide a suitable space 17 to enable the dog 10 to be introduced into and readily removed from the housing. The carriers 3 and t will preferably be made of metal as well as the dog 10 to'increase the strength of the same in a very substantial manner. v The door proper 2 will be formed at opposite ends with the longitudinal slots 18 in which are adaptedto slide and fit the housings 7 of the carriers in such a way that the housings will be completely embedded in the door 2, being made of uniform width therewith, so that the. side plates 5 may bear against one side of the door proper 2 andthe end plate 6.1nay bear against one mensions therewith.

Formed in the opposite sides 19 and 20 of the door proper 2 are the recesses 21 extending into the jambs thereof. These recesseswillbe of sufficient depth to accommodate the serrated bills of the dogs 10.

end of saiddoor, being made of equal di- The pillars 22 span said recesses 21 and are vertically disposed opposite the same, being thinned out intermediate their ends.

From the foregoing construction it will be observed that when it is desired to mount the door proper 2 in position against the door frame the door will be placed against the door frame so as to overly the inner side thereof. The carriers 3 and 4: will have been fitted in the door before the latter is applied against the frame. By forcing the dogs 10 inwardly of the slots 9 a proper distance they may be freely manipulated and slid in said slots in such a way that the bills of said dog will project in said recesses 21 and then, after the pin 14 of the dog shall have been placed in the notches16, said bills 11 may be caught upon the pillars 22, any of the notched parts 13 of said dogs engaging with said pillar in the conventional way. .There is a click 23 pivotally mounted in each of the recesses 21 adapted to engage any of the other notches 12 formed in the bills of said dogs 10 whereby to lock said dogs effectively against movement. When the two dogs shall thus have been looked upon the pillars 22 it will be seen that the door will be held in closed position against the, door frame. By releasing the clicks 23 from locked position the dogs 10 may be detached from the pillars and incased in said'housings 7. By moving the dogs longitudinally in slots 9 the dogs may be separated the proper distance apart to engage with the door jambs of varyingsized door frames.

Numerous modifications may be resorted to in practice without departing in principle from the details of construction herein disclosed.

What I desire to protect and secure by Letters Patent is:

1. In combination, a door frame, a door formed with longitudinal slots, carriers removably inserted into said slots and including side plates adapted to abut the door surface and housings adapted to project through the door, said housings being formed with slots, dogs adapted to be inserted through slots and locked within respective carriers, and means for locking the free extremities of the dogs to said door frame.

2. In combination, a door frame, a door formed with longitudinal slots, carriers adapted to be inserted into said slots and including side and end plates adapted to contact with the door surface and housings, the latter being formed with slots, racks in each housing, locking dogs, a notched bill formed on one extremity of each of said dogs, a pin formed on the other extremities of said dogs and adapted to be inserted through respective housing slots for engagement with respective racks, and means for locking the bill extremities of the dogs to adjacent portions of the door frame.

3. In combination, a door frame a door formed with longitudinal slots, carriers removably mounted in said slots and including housings lying flush with one surface of the door, slots being formed in the houshousings adapted to lie flush with one surface of the door, said housings being provided with slots, racks adjacent the edges of each housing slot, locking dogs formed at one extremity with transverse pins, and at the other extremity with a bill doubly notched on opposite edges, said pins being 'insertible through said slots for engagement with respective housing racks, and means carried by said door frame for locking engagement with both notched edges of each dog bill. o

5. In combination, a recessed door frame, a door, carriers removably arranged within said door and including housings formed with slots, racks in each housing adjacent the slots, dogs adapted to be inserted through said slots for an adjustable locking engagement with said racks, notched bills formed on said dogs to project into said door frame recesses, and means spanning said recesses for an adjustable locking engagement with the dogs projecting thereinto.

7 In combination, a door frame provided with a pair of opposite recesses, a door formed with longitudinal slots, a carrier adapted to be removably inserted into each slot, racks supported within each carrier, locking dogs adapted to project into respective carriers and recesses, a pin carried by each dog for engagement with the racks of the corresponding carrier, a bill formed upon the opposite extremities of each dog with opposite series of notches, a pillar In testimony whereof I aflix my signature spanning each frame recess and adapted to in presence of two Witnesses.
